Self-employed in London? Your income still qualifies.

Q: What transfer tax applies to a $590,550 purchase in London?

About $8,286 at the average. It is paid in cash on closing (or, in Quebec, billed by the municipality afterwards) and cannot be added to the mortgage. An eligible first-time buyer recovers about $4,000 of it through the Ontario relief that applies here. Our land transfer tax calculator runs your own price.

Q: What documents do I need as a self-employed buyer in London?

Everyone brings two years of T1 generals with all schedules, two years of Notices of Assessment, photo ID, 90 days of down-payment history, six months of business bank statements, and a CRA statement of account showing your standing. Then it depends on your structure. A sole proprietor adds two years of T2125, a business licence or registration, and the CRA business number. A partnership adds the partnership agreement and the T2125 showing your share. An incorporated borrower adds two years of T2 corporate returns, T4 and T5 slips, articles of incorporation, corporate financial statements and bank statements, and an accountant's letter confirming ownership and standing. If you are registered for HST, add proof of registration and filing standing. The most common delay on these files is not a missing document — it is an NOA with a balance owing that nobody mentioned until the solicitor ordered the payout statement.

Self-employed mortgages in London — the local picture

London's average price was $590,550 in August 2026. London's business-for-self and commission-income borrowers — common across Old North and Westmount — often show lower line-150 net income than their true cash flow, so we structure add-backs (CCA, home office, vehicle) and shop the Ontario lenders that read a BFS story properly.

Self-employed mortgages: London against the markets around it

The same arithmetic (the 20% this product usually needs) on each market’s own published figure. Rates do not change across the boundary; the price does, and with it the file.

Market	Price	20% down	vs London
London	$590,550 average	$118,110	—
Brantford	$692,096 average	$138,419	+$20,309
Windsor	$541,019 average	$108,204	−$9,906
Sarnia	$535,819 average	$107,164	−$10,946
Chatham-Kent	$429,223 average	$85,845	−$32,265

Each figure is that market’s own board release, as cited on its page. Illustrative arithmetic, not a quote.

Add-backs: qualifying on your real London income

Business-for-self borrowers across London routinely show a lower line-150 net income than their actual cash flow, because good accounting minimizes taxable income. The fix is add-backs: capital cost allowance, home-office and vehicle expenses, and certain one-time deductions can be added back to lift your qualifying income with the lenders that read a BFS story properly.

Here is what that is worth, as an illustrative composite — not a client file and not a promised outcome. A sole proprietor reports $85,000 on line 150. Their return also carries $12,000 of capital cost allowance, $8,000 of home-office expense and $6,000 of vehicle expense — $26,000 of deductions that reduced tax but did not reduce the money that reached the household. Added back, qualifying income becomes $111,000.

What that buys in this market: at 4.39% over 30 years with 20% down, tested at the 6.39% stress-test rate and Ontario's property tax rate, $85,000 of income supports a purchase near $451,000. The same borrower at $111,000 supports about $597,000 — a lift of roughly $146,000 from paperwork that was already in the return.

Set that against the local number: London's $590,550 average needs a household income around $110,000 at the stress-test rate on a 20%-down file. Whether the add-backs close that gap is exactly the calculation we run first, and it is the difference between a decline and an approval on a file where nothing about the business changed. We structure the file — and pick the lender — around the income you actually earn, not just the number at the bottom of your return.

Self-employed mortgages across London

From Old North to Oakridge, the dominant property form in each pocket changes how a self-employed file is underwritten.

Old North, Westmount, Byron, Wortley Village, Oakridge

Century detached near the university · 1960s–80s detached subdivision · Established detached beside the river valley · Century detached and semi, heritage character · Post-war and 1970s detached

Established stock is where business-for-self owners most often hold long tenure and real equity, and equity is what widens the lender list when line 150 understates the actual cash flow.

Hyde Park

Newer detached and townhouse subdivision

A builder purchase needs the rate hold to reach final closing, and a business-for-self file underwrites more slowly than a salaried one — the two timelines have to be planned against each other, not discovered in sequence.

Masonville

Detached and condo near the university and hospital

A condominium adds the corporation's review on top of an income story that already takes longer to document, so a business-for-self file on a condo should start earlier than a salaried buyer's would.

London market

What London’s market means for your self-employed mortgage.

London's student-rental market is a rental-income underwriting question

A large share of London's investor activity clusters around the university and college catchments, and buying a property to rent by the room is not underwritten the way a single-tenant rental is. Two things decide these files. The first is how the lender counts the rent: a rental add-back adds roughly half the gross rent to your income, while a rental offset nets a larger share — often around 80% — directly against the property's carrying cost. On a property whose rent is strong relative to price, which is the usual London case, the offset method is materially more generous and can be the difference between qualifying and not. The second is what the property legally is. A house rented to several unrelated students may be a lodging house under the municipality's licensing regime, and a lender's willingness to fund it — and an insurer's willingness to cover it — turns on that classification rather than on how the listing describes it. A non-owner-occupied rental also cannot be default-insured, so 20% down is the floor regardless of price. The exception worth knowing is the owner-occupied multi-unit rule: an owner-occupied duplex can use the insured tiered minimum (5% on the first $500,000, 10% above), and an owner-occupied triplex or fourplex can be insured with at least 10% down, on purchases up to $1.5 million — which in a market at London's price points is a genuinely different entry point.

Older stock, insurability, and what closing actually costs in London

London's character housing — Old North, Wortley Village, the streets around the university — is part of the city's appeal and a recurring source of financing friction. Knob-and-tube wiring, galvanised or lead supply plumbing, an aged oil tank, or a roof near the end of its life can all affect whether a property insurer will bind coverage. That matters more than it sounds: a lender will not advance funds on a home that cannot be insured, so an insurability problem is a mortgage problem even when the mortgage approval itself is clean. Where the work is planned rather than avoidable, a purchase-plus-improvements structure lets the lender advance against the as-improved appraised value, with the improvement money held back and released once the work is verified — which requires quotes up front and enough cash to carry the job in the meantime. On closing costs, London sits in Middlesex County and pays Ontario land transfer tax only; there is no municipal land transfer tax of the kind the City of Toronto charges. At London price points the first-time-buyer rebate of up to $4,000 therefore covers a substantial share of the entire bill, sometimes all of it. Budget the rest of the stack — legal fees, title insurance, inspection, appraisal, prepaid-tax adjustments — at roughly 1.5% to 4% of price.

An illustrative London file: the rent was real, the classification wasn't

This is an illustrative composite assembled from the rules above — not a specific client, and not a promised outcome. An investor budgets a London purchase around per-room student rent, which on paper more than services the mortgage. The file runs into two separate walls. First, the lender applies a rental add-back rather than an offset, counting roughly half the gross rent toward income instead of netting most of it against carrying costs — and the debt-service ratios, tested at the stress-test rate, no longer clear. Second, the property's use may require municipal licensing that the seller does not hold, which narrows both the lender list and the insurance options. Neither problem is about the borrower. Both are answerable before an offer: ask which method a lender uses before choosing one, and confirm the property's classification and licensing status rather than inferring it from the current tenancy. Run the same buyer at an owner-occupied duplex under the federal 2-to-4-unit policy and the entry cost falls dramatically. Every real file is assessed on its own facts.

FAQ

What does a self-employed mortgage work out to on London's August 2026 average price?

Middlesex & Elgin average residential price, London and St. Thomas Association of REALTORS® (via CREA) put the London average at $590,550 for August 2026. For a self-employed mortgage that makes the 20% down about $118,110 (the 20% this product usually needs). The same board counted 526 London sales in August 2026. Your own property and balance replace these numbers on the file.

How does London compare with Brantford, Windsor and Sarnia for a self-employed mortgage?

On each market's own cited figure, the 20% down is $118,110 in London against Brantford $138,419 (average $692,096); Windsor $108,204 (average $541,019); Sarnia $107,164 (average $535,819). The comparison is the same arithmetic on a different price, which is why moving the search one municipality over changes the file before it changes the rate — lenders price the same product the same way across Ontario.

What transfer tax applies to a $590,550 purchase in London?

About $8,286 at the average. It is paid in cash on closing (or, in Quebec, billed by the municipality afterwards) and cannot be added to the mortgage. An eligible first-time buyer recovers about $4,000 of it through the Ontario relief that applies here. Our land transfer tax calculator runs your own price.

What's the average self-employed file size in London?

London's average price is approximately $590,550, so the typical self-employed file we see here sits in the $501,968–$679,133 band. Your specific neighbourhood and property type can move that materially.

What does a self-employed mortgage cost on a typical London home?

On London's $590,550 average price, a representative self-employed file at minimum down works out to about $118,110 down and roughly $2,352/mo (principal + interest at 4.39% over a 30-year amortization), plus about $8,286 in Ontario land transfer tax. Your exact numbers depend on the property and your file — we run them precisely before you commit.

Why use a London mortgage broker for a self-employed mortgage?

A local broker knows Southwest ON's property types and which of our 100+ lenders price self-employed files best in London — from Old North and Westmount condos to detached stock — and there's no fee to you on A-lender files. The regional lenders on that panel are listed under the neighbourhood table above.

What documents do I need as a self-employed buyer in London?

Everyone brings two years of T1 generals with all schedules, two years of Notices of Assessment, photo ID, 90 days of down-payment history, six months of business bank statements, and a CRA statement of account showing your standing. Then it depends on your structure. A sole proprietor adds two years of T2125, a business licence or registration, and the CRA business number. A partnership adds the partnership agreement and the T2125 showing your share. An incorporated borrower adds two years of T2 corporate returns, T4 and T5 slips, articles of incorporation, corporate financial statements and bank statements, and an accountant's letter confirming ownership and standing. If you are registered for HST, add proof of registration and filing standing. The most common delay on these files is not a missing document — it is an NOA with a balance owing that nobody mentioned until the solicitor ordered the payout statement.
